摘要： A serial buffer having a plurality of virtual queues, which can be allocated to include various combinations of on-chip dual-port memory blocks, on-chip internal memory blocks and/or off-chip external memory blocks. The virtual queues are allocated and accessed in response to configuration bits and size bits stored on the serial buffer. Relatively large external memory blocks can be allocated to virtual queues used for data intensive operations, while relatively small and fast dual-port memory blocks can advantageously be allocated to virtual queues used for passing command and status information. The serial buffer provides an efficient and flexible manner for utilizing available memory, which not only minimizes the access latency but also provides a large amount of buffer space to meet different application needs.

摘要： On-chip resources of a serial buffer are accessed using priority packets of a Lite-weight protocol. A priority packet path is provided on the serial buffer to support priority packets. Normal data packets are processed on a normal data packet path, which operates in parallel with the priority packet path. The system resources of the serial buffer can be accessed in response to the priority packets, without blocking the flow of normal data packets. Thus, normal data packets may flow through the serial buffer with the maximum bandwidth supported by the serial interface. The Lite-weight protocol also supports read accesses to queues of the serial buffer (which reside on the normal data packet path). The Lite-weight protocol also supports doorbell commands for status/error reporting.

摘要： A serial buffer monitors an incoming stream of packets to identify single missing packets and multiple consecutive missing packets. Upon detecting multiple consecutive missing packets, an interrupt is generated, thereby stopping the data transfer. Upon detecting a single missing packet, a single missing packet identifier is inserted into the packet header of the packet that resulted in identification of the single missing packet. The incoming packets, including any inserted single missing packet identifiers, are written to a queue. When the water level reaches the water mark of the queue, the stored packets are read to create an outgoing packet stream. When a packet read from the queue includes an inserted single missing packet identifier, a dummy packet (e.g., a packet having a data payload of all zeros) is inserted into the outgoing packet stream. As a result, real-time applications are capable of processing the outgoing packet stream in a constant fashion.
摘要翻译：串行缓冲器监视传入的数据包流，以识别单个丢失的数据包和多个连续的丢失数据包。在检测到多个连续丢失数据包时，产生中断，从而停止数据传输。在检测到单个丢失的分组时，将单个丢失的分组标识符插入到分组的分组报头中，导致单个丢失分组的标识。传入的数据包，包括任何插入的单个丢失的数据包标识符，被写入队列。当水位达到队列的水位时，读取存储的数据包以创建输出数据包流。当从队列读取的分组包括插入的单个丢失的分组标识符时，将虚拟分组（例如，具有全零的数据有效载荷的分组）插入到输出分组流中。因此，实时应用能够以恒定的方式处理输出分组流。
